Display selected autonomous mode on the robot? #26
Description
This is something I've been hoping to have for years. Maybe it is low priority, like a side project or a stretch goal. It could be a fun little project for someone interested in the electronics side of things and less interested in FRC robot code.
It would be nice to have a visual display on the robot, somewhere near the autonomous selector switch, that indicates the currently selected autonomous mode. It could be as simple as an LED display showing a number between 0 and 11, but it could be more complex, like an LED display that displays a short text description, like "0 - do nothing".
I was thinking that one way to do this would be to attach a screen to the Raspberry Pi running vision. It would be driven by a small program running on the Pi that would listen on networktables, and the robot code would publish the autonomous selector switch output and maybe a string. The pi would just display whatever is being published to the network tables.
This simple little round-trip communication would prove that a lot of things are working, such as IP connectivity between the Pi and the Rio, and that code is up and running on both.
